Lengthening a Frame to add a axle

Just curious if anyone has any info on someone that will Lengthen my frame or does this professionally. I'm interested in paying someone. I understand the liabillty. I also know it get's done all the time, and with the proper procedures it is not only do-able, but just as safe as at least 95% of the trucks running down the road today
lots of people are doing frame stretching but looking for someone in texas dont want to be down that long any phone numbers will help

 

i dont know of anyone in Texas. I live in Missouri near Kansas City MO. i have a 2000 t600 that i had 14 inches of stretch put in to put a lift axle on. with buying the axle and the frame stretch cost me $6500. they put a piece of frame inside mine and welded it to the truck frame. the axle was then mounted over where they stretched the truck. the name of the company that did mine is called custom truck sales in Kansas City. (816) 241-8380. you might call and see if they have a place in Texas or if maybe they know of someone in your area.

 

My opinion is don't allow the frame to be cut and piece "grafted" in. The cost is less doing it this way but, you get what you pay for. The best way is have the shop add to the rear of the frame, then move the axles back, doing it this way allows you to get the spacings the way you want. Those spacings will make a difference (western states) in how much weight can be permited on the tridum. A standard spread is 52" and the western states will hammer you on weight. Also the frame won't have that weak spot.

 

That seems to be the DOT new pet peave. If the extra axle is not on the data plate, its dis allowed as far as using it for the additional weight. The only way to get the data plate changed from the manufacture is to also add the heavy duty front axle, tires, etc

 

A local dirt contractor used to buy damaged day cabs and lengthen their frames to make his 14 yard dump trucks. What he did was to splice in the extra length, yet also on the inside of the frame was a second frame rail that was bolted on the inside carrying the joint to 2 feet plus on each end of the new joint.

I seem to remember some where in the training for class 8 driving that we are not allowed to weld or drill holes int the existing frame. That any new additions must be U-bolted. Drilling or welding on the frame will fatigue it.

Maybe we can get one of the lurking diesel mechanics to weigh in on this?

 

give Houston Trucking Rigging a call 713-673-4109, or southwest truck rigging 713-939-1234. or look them up on the web. good luck!

 

Not sure what you mean. There is no regulation on adding an axle. There is state laws as to how much weight is allowed depending on the spread between the group. For example in WA 4'7" between axles (tridum) is 59,860 LBS and 60" is 65,000 LBS.

the tag your talking about you can buy or get for nothing at most fab shops that in stall dump beds or reconfigure trucks you dont have to replace the front axle. i got mine from a shop at home for free and typed in the info myself.

 

I have cut frames and added sections, We cut in front of the front axle and added their, then re drilled the frame to take the front axle. 99% of frame extensions are taking a tractor and turning it to a truck or motor home.
As was stated most every place you go to or person that stops you has a computer and a licence plate scanner, that gives them the original serial number, and build sheet.
That allows every one that stops you to demand an inspection because of the modification done to the original vehicle.
By the time you add the section and axle you could buy a tandem. You really do want to do a lot of checking in every state you drive threw, before you start.
Just a thought!
